Abstract

Le procédé consiste à immerger les pièces ayant subi au préalable une diffusion thermochimique du type soit nitruration, soit sulfonitruration, soit carbonitruration, dans un bain de sels fondus composé de carbonates, nitrates, hydroxydes, ainsi que sels oxygénés de métaux alcalins, les quantités relatives pondérales anioniques de carbonates, nitrates et hydroxydes, exprimées pour des sels de sodium et correspondant à la phase active c'est-à-dire liquide du bain, étant les suivantes: (CF DESSIN DANS BOPI) tandis que la quantité pondérale de sels oxygénés de métaux alcalins exprimée en équivalent Cr2 O7 2 - est la suivante: (CF DESSIN DANS BOPI) Ce procédé permet de garantir un degré élevé de reproductibilité des résultats quelque soit le type de pièces traitées.
